California farmers continue to outproduce every state in the nation despite shrinking farm acreage. According to Harold O. Carter, aprofessor of agricultural economics at UC Davis, this is due to diverse land resources, fertile soil and a forgiving climate that allow year-round production of an impressive array of crops. "To this farmers add sophisticated technology and management systems, which allow them to produce and market superior agricultural products," says Carter, who recently co-authored a report on California agriculture. California exceeds the national average in yields per harvested acre in major crops, and has more than double the U.S. per-acre yields of cotton and winter wheat. Even in a year when total farm revenues dipped, exports of California farm products in 1991 rose to new highs, bringing in a record $4.66 billion. Carter says the upswing in agricultural exports is due mostly to higher sales in the Pacific Rim and the European community. Factoring in multiplier effects, farming and related activities generated $63.1 billion, or 9 percent of California's $697 billion gross state product in 1991. Carter and UC Berkeley professor George Goldman recently presented their report to the California State Board of Food and Agriculture.
